Helen Strickland is attending a memorial service for her husband, Craig, on Tuesday evening, after the country singer and his friend died during a recent hunting trip. On Monday, she shared a heartbreaking photo while also asking fans for prayers.

"I can do all things through Christ who strengthens me," wrote Helen, citing Bible verse, Philippians 4:13. "Dear friends, please pray that I may have strength tomorrow as I walk through the most difficult experience I've ever gone through in my life."

"I am so thankful for every moment I had with Craig and I am thankful the Lord is taking care of him now," she continued. "More than ever our family will need your prayers. I'm so thankful for every person that has poured out their love to us. If you are unable to physically attend, I hope that you will join our family via webcast at crosschurch.com/watchlive. I love you all as Craig did. Goodnight."

The Backroad Anthem singer's memorial is being held in Rogers, Arkansas at 6 p.m., and being streamed online for those who cannot attend.

On Jan. 4, the Oklahoma Highway Patrol Marine Enforcement Division recovered Craig’s body in an area referred to as Bear Creek Cove. The 29-year-old singer and his 22-year-old friend, Chase R. Morland, were first reported missing following a duck hunting trip. Chase’s body was found on Dec. 28.

Last week, the former Miss Arkansas USA remembered her last moments with Craig.

"He walked out the door and he looked at me and said, 'I love you,'" Helen told CNN. "He blew me a kiss, and said 'I'll talk to you soon,' and he walked out."

"I would never, I wouldn't change anything about that, and I think the family would say the same thing," she continued. "That entire time that we were with family, it was like he knew exactly what each family member needed to make them feel OK about his passing, and every person felt loved and they wouldn't change a thing."
